ABOVE: From left, Graydon Abel, Eero White, Michael White and Jill White observe a minute of silence Friday at the University of Colorado Boulder at the end of a memorial ride for Magnus White, who was killed by a driver on the Diagonal Highway in 2023. Members of the Pi Kappa Alpha fraternity at the University of Colorado Boulder rode a stationary bike for 8,423 straight minutes, with each minute symbolizing one of the cyclists and pedestrians killed by drivers in 2023. They finished Friday at 12:28 p.m., the exact time of day when White was killed. The money raised went to the White Line Foundation, which was founded in Magnus White’s honor by his parents.
